Title: Improvements in or relating to zig-zag sewing machines
IPC: D05B3/02
Filed: 1959-11-23
Abstract: 875,546. Sewing machines. PFAFF A. G., G. M. Nov. 23, 1959 [Nov. 24, 1958], No. 39601/59. Class 112 In a zig-zag sewing machine two rigidly connected and angularly movable follower members are adapted to co-operate with respective ones of a pair of cams which are mounted on a stitchwidth setting shaft and control stitch widths of different magnitudes. An arm 11 is journalled at one end upon a fixed shaft 12 and journals at its other end a shaft 9. The angular position of the latter relative to arm 11 determines the stitch width, and the angular position of arm 11 determines the centre line of the stitches. An arm 13, adjustably fixed to arm 11, is formed with a follower portion 16 which is biased against a cam 17 by a spring 18 acting on an arm 19 rigid with arm 11. Cam 17 is fixed to a hollow shaft 20 which is journalled in a fixed block 22 and carries a handle 27 which may be held in any one of three positions by ball catch means 31, 32. Cam 17 is formed with portions 33, 34, 35, which correspond to said positions and determine respectively a left hand, central and right hand position of the stitches. A sleeve 36, clamped to shaft 9, is connected by a link 38 to a sleeve 40 journalled on shaft 12. The angular position of sleeve 40 thereby determines the stitch width irrespective of the angular position of arm 11. A sleeve 44, journalled on shaft 12, is formed with arms 41, 42, 43. A spring 54, connected between arm 42 and a lug 53 on sleeve 40, biases a lug 55 on sleeve 40 against a screw 56 carried adjustably by arm 42. A hollow shaft 51, journalled in shaft 20, carries at one end cam members 47, 48, and at the other end an operating knob 52. A shaft 61, journalled in shaft 51, carries at one end a cam member 63 and an arm 68, and at the other end a handle 65. A spring 45, acting on arm 43, biases arm 42 into engagement with cam 47. A spring 67, weaker than spring 45, acts on arm 68 to engage cam 63 with a lateral extension 69 on arm 42. When knob 52 is operated to turn shaft 51 clockwise, cam 47 co-operates with arm 42 to turn sleeve 44 for increasing the stitch width. If, at any setting of knob 52 from zero to half of the maximum stitch width, handle 65 is operated to turn shaft 61 clockwise, cam 63 co-operates with extension 69 to lift arm 42 from cam 47 and to engage arm 41 with a cam surface 70 on cam 48, whereby a stitch width of twice the value as that set by knob 52 is produced. If handle 65 is operated to turn shaft 61 counter-clockwise, cam 63 engages lug 53 to turn sleeve 40 clockwise for decreasing the stitch width up to zero value. Cam 48 is formed with a surface 71 such that, in the zero position of knob 52, when shaft 61 is turned clockwise, arm 41 will move past surface 71 through the entire range of stitch widths. Arms 19 and 43 are formed with apertures 73, 74 75, adapted, it is stated, to co-operate with known means for controlling the stitch width and position automatically.

Title: Laminated Soundboard for a String Instrument.
IPC: G10C3/06
Filed: 1968-08-22
Abstract: 1,177,463. Stringed musical instruments. C. G. CONN Ltd. 22 Aug., 1968 [29 Sept., 1967], No. 40224/68. Heading G5J. A laminated soundboard for a stringed musical instrument comprises a core 25 formed from a low density structure such as a paper honeycomb, resin impregnated glass, paper or cotton phenolic laminate or metal, sandwiched between skins 20 and 22 having a high modulus of elasticity such as epoxy or plastics or metal sheeting, the soundboard having a bridge attached thereto across which the strings are stretched. The skins are attached to the core either by means of a liquid adhesive or using a sheet 30 of thermo-setting glue. Alternatively, an open weave cloth, such as fibreglass matting, is impregnated in a liquid adhesive so that the combination forms both the adhesive and the skins 20 and 22. Two methods of mounting the soundboard are described (Figs. 4 and 5, not shown). In one construction the soundboard is bent to form a crown at (40) and is supported at the two straight edges. The soundboard is bent by employing skins 20 and 22 of different materials such that when the structure is heated the different coefficients of expansion will cause bending. In the other construction (Fig. 5), a bridge is attached to the soundboard and is connected to the strings of the instrument, the soundboard is being supported merely on the strings.

Title: Fastener driving machine
IPC: B25C1/04
Filed: 1965-09-21
Abstract: 1,097,540. Nailing and stapling machines. W. SCHAFROTH. Sept. 21, 1965 [Sept. 25, 1964], No. 40263/65. Heading B4C. A fastener-driving machine such as for driving nails or staples comprises a driver 5 connected to a piston 33 which is slidable in a cylinder 13, a valve block V being mounted below the cylinder and having a valve 66 adapted to close an exhaust opening 17 and allow air from a reservoir 9 to return the piston after a working stroke. The valve 66 is connected with the air in the reservoir via passages 62, 64, Figs. 9, 13 (not shown), a valve 57, tube 50a, chamber 36 and a passage 53; the valve 66 is normally loaded to the open position shown by means of a spring 68 surrounding a pressure adjusting rod 67, clearance being provided between the rod and the valve. A main control valve 20, which may be of nylon, is mounted in the chamber 36 and is arranged to either close the open top of the cylinder and open an exhaust port 31 or the reverse. In operation, with the machine in the position shown, air from the reservoir 9 passes through the passage 53, a trigger-operated ball valve 43 and chamber 36 to maintain the valve 20 closed; air also flows through the pipe 50 and holds the valve 57 closed so that the exhaust valve 66 remains open. Upon actuation of the trigger 2, the ball valve is lifted off its seat so that the air in the chamber 36 is exhausted through a passage 42. The valve 20 then opens and allows the air to enter the cylinder so as to drive the piston on its working stroke, the air in front of the piston being exhausted through the opening 17. Soon after the start of the stroke the driver 5 abuts a slide 72 which opens the valve 57 thereby allowing air to close the exhaust valve 66. When the trigger is released the ball re-seats and so permits the valve 20 to close the cylinder top and open the exhaust passage 31. Air then flows through the clearance between the adjusting rod 67 and the valve 66 so as to return the piston; at the end of the return stroke the slide 72 is released and allows the valve 57 to close. A safety valve 84 Fig. 5a (not shown) normally prevents actuation of the machine until it is closed by means of a lever 82 operated when a sliding foot 80 is pressed against a workpiece.
